Furthermore, there is dreck out there in the SSD market, so if you opt not to buy my recommended OWC solid state drives, at least test what you do buy.

I test my drives using the DiskTester fill-volume command, part of my software, diglloydTools. DiskTester fill-volume outputs data that can be pasted into a supplied Excel spreadsheet for an instant graph, and it’s good for hard drives or SSDs.
